We analyze a two country-two good model of international trade in which citizens in each country differ by their specific factor endowments. The trade policy in each country is set by the politician who has been elected by the citizens in a previous stage. Due to a delegation effect citizens generally favor candidates who are more protectionist than they are. The one-candidate-per-country equilibria exhibit a “protectionist drift” owing to this delegation effect. In addition, we find an additional source of protectionist drift that we call the “abstention effect”. Not only do candidates wish to delegate to more protectionist colleagues, but these more protectionist colleagues who can win election, prefer still more protectionist candidates than themselves. Therefore, they have an incentive to abstain, that is, not run for election. We show that because of this abstention effect there exists a range of electable citizens all of whom are more protectionist than the median voter's most preferred candidate. We extend the analysis allowing two-candidate equilibria and the possibility that there are costs and benefits of holding office. 相似文献

We analyse the issue of firm-sponsored training under product market imperfections. In this setting, qualification becomes a public good for firms when their profits are increasing in the stock of skilled workers but remains a private good to students/workers. Students have to pay a tuition fee but at the same time firms sponsor education: universities sell training to both. We prove that the proportion of skilled workers is larger in more competitive economies/industries while the share of firms in the financing of training is a monotonically decreasing function of the degree of competition. An increase of the latter indeed increases the equilibrium skilled wage while reducing its sensitivity to an increase of the supply of skilled workers. The firms’ aggregate expenditures on training per worker are nevertheless a nonmonotonic function of the competitiveness of the economy. 相似文献

Identifying unambiguously the presence of a bubble in an asset price remains an unsolved problem in standard econometric and financial economic approaches. A large part of the problem is that the fundamental value of an asset is, in general, not directly observable and it is poorly constrained to calculate. Further, it is not possible to distinguish between an exponentially growing fundamental price and an exponentially growing bubble price. In this paper, we present a series of new models based on the Johansen–Ledoit–Sornette (JLS) model, which is a flexible tool to detect bubbles and predict changes of regime in financial markets. Our new models identify the fundamental value of an asset price and a crash nonlinearity from a bubble calibration. In addition to forecasting the time of the end of a bubble, the new models can also estimate the fundamental value and the crash nonlinearity, meaning that identifying the presence of a bubble is enabled by these models. In addition, the crash nonlinearity obtained in the new models presents a new approach to possibly identify the dynamics of a crash after a bubble. We test the models using data from three historical bubbles ending in crashes from different markets. They are the Hong Kong Hang Seng index 1997 crash, the S&P 500 index 1987 crash (Black Monday) and the Shanghai Composite index 2009 crash. All results suggest that the new models perform very well in describing bubbles, forecasting their ending times and estimating fundamental value and the crash nonlinearity. The performance of the new models is tested under both the Gaussian residual assumption and non-Gaussian residual assumption. Under the Gaussian residual assumption, nested hypotheses with the Wilks' statistics are used and the p-values suggest that models with more parameters are necessary. Under the non-Gaussian residual assumption, we use a bootstrap method to obtain type I and II errors of the hypotheses. All tests confirm that the generalized JLS models provide useful improvements over the standard JLS model. 相似文献

Several studies document that low-educated workers participate less often in further training than high-educated workers. This article investigates two possible explanations: low-educated workers invest less in training because of (1) the lower economic returns to these investments or (2) their lower willingness to participate in training. Controlling for unobserved heterogeneity, we find that the economic returns to training for low-educated workers are positive and not significantly different from those for high-educated workers. However, low-educated workers are significantly less willing to participate in training. We show that this lesser willingness to train is driven by economic preferences, and personality traits. 相似文献

Social partnership in Ireland has attracted considerable international attention. This paper examines the origins, focus, and institutional architecture of the Irish social partnership model. The paper also examines social partnership in the context of the theory of social pacts and suggests that the institutionalization of social partnership can be attributed to the continuing significance of compensatory political exchange, the influences of partnership networks, and the effects of new mechanisms for conflict resolution. 相似文献

Insurance has for a long time been perceived as a way of transferring responsibility from insured agents to insurers and thus as potentially influencing insured agents' behavior. Two particular opportunistic behaviors have been analyzed. First, the theory of adverse selection predicts that high-risk agents are likely to demand more insurance than are low-risk agents. Second, the theory of moral hazard predicts that the wider the insurance coverage, the less agents will try to prevent accidents. Both theories thus conclude that agents who are totally insured should have a higher probability of accident than those with only partial insurance, ceteris paribus. Nevertheless, one of the aims of insurance rating systems is to control for these opportunistic behaviors. In this article, we use individual data to see if the French automobile insurance rating system has achieved this aim. We do this using a two-step maximum-likelihood method. First, we compute a probit model to estimate the probability of taking out comprehensive versus third-party insurance. We then calculate the generalized residual, which is included as an independent variable in a negative binomial model estimating the probability of having an accident. The coefficient of this variable is argued to represent adverse selection and ex-ante moral-hazard behavior. 相似文献

In this paper we address the following question: is it more profitable, for an entrant in a differentiated market, to acquire an existing firm than to compete? We illustrate the answer by considering competition in the banking sector. 相似文献
